This reverts commit e5de9ea779.

The patch introduced `map__zput(new_node->map)` in the kcore load
path, causing a segmentation fault when running `perf c2c report`.

The issue arises because `maps__merge_in` directly modifies and
inserts the caller's `new_map`, causing it to be freed prematurely
while still referenced by kmaps.

Later branchs (6.12, 6.15, 6.16) are not affected because they use
a different merge approach with a lazily sorted array, which avoids
modifying the original `new_map`.

Fixes: e5de9ea779 ("perf dso: Add missed dso__put to dso__load_kcore")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
